Recovery of retinal sensitivity after transient branch retinal artery occlusion

A 66-year-old man with hypertension and branch retinal artery occlusion in the right eye with a visual acuity of 20/20 underwent sequential investigation with fluorescein angiography, optical coherence tomography, and microperimetry to evaluate the retinal sensitivity overlying an area of branch retinal artery occlusion. On follow-up, clinical resolution of retinal whitening and thickening was noted in the affected area. Optical coherence tomography revealed retinal thinning and inner retinal atrophy and microperimetry showed improvement in retinal sensitivity (11 db) overlying the area of branch retinal artery occlusion following resolution of retinal edema.
